Re: depressing
So why not learn? You have plenty of time to learn, in fact people never stop learning and developing skills. Just because you don't do these things now it doesn't mean that you will have difficulty in picking them up quickly. They're actually quite simple tasks, try not to over think them and get on with doing them.
You can't blame your mum. Unfortunately as children we complain when our parents tell us to do something and then when we're not told to something we blame them for not forcing it upon us. If you're educated then you are old enough to have done these things of your own initiative.
